Retail Requirements

Before you install Uyuni for Retail, ensure your environment meets the minimum requirements. This section lists the requirements for the Uyuni for Retail installation.

Review also general requirements of the Uyuni listed at General Requirements.

Uyuni for Retail is tested on x86-64 architecture.

1. Server Requirements

Table 1. Server Hardware Requirements
Hardware	Details	Recommendation
CPU	x86-64	Minimum 4 dedicated 64-bit CPU cores
RAM	Minimum	16 GB
	Recommended	32 GB
Disk Space	`/` (root directory)	40 GB
	`/var/lib/containers/storage/volumes`	Minimum 150 GB (depending on the number of products)
	`/var/lib/containers/storage/volumes/var-pgsql`	Minimum 50 GB
Swap space	Systems can benefit from additional swap space. SUSE recommends using a swap file instead of a swap partition. For more information about swap space, see installation-and-upgrade:hardware-requirements.adoc#installation-swap-space.	8 to 12 GB

Uyuni performance depends on hardware resources, network bandwidth, latency between clients and server, etc.

Based on the experience and different deployments that are in use, the advice for optimal performance of Uyuni Server with an adequate number of proxies is to not exceed 10,000 clients per single server. It is highly recommended to move to the Hub setup and involve consultancy when you have more than 10,000 clients. Even with fine-tuning and an adequate number of proxies, such a large number of clients can lead to performance issues.

For more information about managing a large number of clients, see Multiple Servers with Hub to Manage Large Scale Deployments.

2. Branch Server Requirements

Table 2. Branch Server Hardware Requirements
Hardware	Details	Recommendation
CPU	x86-64	Minimum 2 dedicated 64-bit CPU cores
	Recommended	The same as minimum values
RAM	Minimum	2 GB
	Recommended	8 GB
Disk Space	`/` (root directory)	Minimum 40 GB
	`/var/lib/containers/storage/volumes`	Minimum 100 GB
Swap space	Systems can benefit from additional swap space. SUSE recommends using a swap file instead of a swap partition. For more information about swap space, see installation-and-upgrade:hardware-requirements.adoc#installation-swap-space.	4 to 8 GB

3. Build Host Requirements

Table 3. Hardware Requirements for Build Host
Hardware	Recommended
CPU	Multi-core 64-bit CPU
RAM:	Test Server Minimum 2 GB
	Production Server Minimum 4 GB
Disk Space:	`/` (root) Minimum 24 GB
	`/var/lib/Kiwi` Minimum 15 GB

4. Network Requirements

The Uyuni Server requires a reliable and fast WAN connection.
The branch server requires a reliable WAN connection, to reach the Uyuni Server.
If you are using a dedicated network, the branch server requires at least two network interfaces: one connected to the WAN with a reachable Uyuni Server, and one connected to the internal branch LAN.
Terminals require a LAN connection to the branch server network.

5. POS Terminal Requirements

Table 4. Hardware Requirements for Terminals
Hardware	Recommended
RAM:	Minimum 1 GB for hosts that need to run OS images built with Kiwi (PXE booted or not)
Disk Space:	Disk space depends on size of the OS image
